This is a list of NMSSM spectrum calculators that are currently under investigation, with a small summary of their main features:

full 2-loop RGEs; full 1-loop corrections to all SUSY masses; 2-loop Higgs corrections O(alpha_s alpha_t + alpha_s alpha_b + alpha_tau^2 + alpha_t^2 + alpha_t alpha_b + alpha_b^2); Z3-invariant and Z3-violating NMSSM; boundary conditions and EWSB output can be customized via a modelfile

Real and complex NMSSM: Higgs boson masses up to O(alpha_t alpha_s), branching ratios including the state-of-the-art HO (QCD, SUSY-QCD&EW - Delta_b?, Delta_s Delta_tau; , SUSY-QCD to ~q decays) corrections and off-shell decays.

2-loop RGEs; computation of the Higgs (up to O((alpha_b + alpha_t)alpha_s)) and sparticle masses and decay ratios, and the dark matter relic density via MicrOmegas. Possible variants are the general NMSSM, the Z3-invariant NMSSM, constraints at the GUT scale and GMSB. Present experimental constraints are implemented.

full 2-loop RGEs; full 1-loop corrections to all SUSY masses; 2-loop Higgs corrections O(alpha_s alpha_t + alpha_s alpha_b + alpha_tau^2 + alpha_t^2 + alpha_t alpha_b + alpha_b^2); Z3-invariant and Z3-violating NMSSM; a number of boundary conditions (mSUGRA, non-universal trilinears, general, ...)

2-loop RGEs with flavour and CP effects; 1-loop corrections to all SUSY masses; 2-loop Higgs corrections beyond O(alpha_s(alpha_b + alpha_t)); independent calculation of decays as well as flavour and precision observables.

Definition: alpha_t,b=h_t,b^2/(4pi), with h_t,b being the superpotential top and bottom couplings. The one-loop O(alpha_t) corrections are in fact corrections proportional to h_t^2 m_t^2, i.e. h_t^4 v2^2.
